Abstract

Overdistension of the hand-forearm veins after a period of ischaemia-induced stasis causes local pain in a high percentage of migraineurs, but never in healthy subjects. To investigate the mechanism of such pain, we compared 5-hydroxytryptamine (5HT) whole blood levels and hand vein 5HT reactivity of migraine subjects who did experience pain during venous overdistension to those who did not. No differences were found in whole blood 5HT levels or in the venoconstrictor activity of 5HT between subjects experiencing pain and those who did not. No correlation was found between whole blood 5HT levels and the degree of 5HT-induced venoconstriction. Our results suggest that, if platelets are considered as a model of central antinociceptive 5HT neurons, pain appearance is not due to reduced 5HT at a central level and, therefore, to increased perception of peripheral nociceptive stimuli. Moreover, the similar 5HT venoconstrictive effect (indirect marker of venous tone and, therefore, of venous distensibility) seems to indicate that a mechanical factor is not involved in pain appearance during the HAVD test.
